    abstract = {Phytochemical compounds and anti-microbial properties of the methanol extracts of <I>Rhoicissus revoilli</I>  (Vitaceae) were studied between January and December 2007 at Maseno University, Kenya. The bacterial used for the antimicrobial analysis consisted of clinical strains of <I>Streptococcus pryogenes</I> (gram positive) and S<I>almonella typhi</I> (gram negative) bacteria and one strain of fungi (<I>Aspergillus niger</I>). The methanol extract was active against the 3 microorganisms. Root extracts showed greater microbial growth inhibition in  comparison  to  leaf  extracts.  The  phytochemical  screening  for  the  plant leaves and roots of <I> R. revoilli</I> revealed the presence of active compounds of flavonoids, alkaloids, saponin, steroids and antharaquinones. The results from the present study have shown that the species of <I>Rhioicissus revoilli </I>have considerable activity against the gram negative bacteria <I>Salmonella typhi</I>, gram positive bacteria <I>Streptococcus pyrogenes</I> and one fungal strain <I>Aspergillus niger</I>. <I>Streptococus pyrogenes</I> experienced lesser growth inhibition with root extracts compared to the other 2 microbes. It is possible that the growth inhibition observed in the study occurred due to the presence of different chemical compounds. Absence of tannins in roots but not leaves could explain the greater growth inhibition of <I>S. typhi</I> and <I>A. niger</I>. Pit method was a better method for testing antimicrobial activity than disc method in the study.}
